They curve the lens which impacts focusing ability, they are also heavy on the bridge of your nose meaning that you feel that they are there more, and the lenses are smaller that the "ugly" ones, meaning that you never get fully immersed into the image.

Not that they are terrible, but just some of the trade-offs to get stylish glasses with a brand stamped on them that you will be only wearing in a dark room where nobody will really see them.

Unfortunately, every time I want to watch 3d I have to bypass my 3808, and then run sound from the ps3 via optical out and lose out on Dolby true hd or dts hd master audio. Plus it is a PITA to reconfigure it every time. I need to upgrade my receiver.

They are apparently the exact same glasses as the Optima BG-ZF2100GLS, but cheaper. They come with a RF emitter in the 'starter kit', and a charging cable. They are compatible with the MV glasses, as they are made by Bit Caldren. The IR input cable is for Optima and will not work with my Sony projector. I had to find a MV IR sensor to use. The MV IR sensor is just a widget that is placed near the projector's IR emitter. It then syncs to the projector IR output and sends that to the little RF emitter. Works pretty slick.

Tried them last night watching Ice Age, Continental Drift. They worked flawlessly. I gotta admit, the 3D image is pretty amazing. Better than I've ever seen before, including Disney World attractions.
